Dyes: Industrial scale up
This is a worksheet which looks at various factors which effect the scaling up of laboratory processes to industrial scale in the commercial manufacture of dyes. Students look at
- costs of the raw materials for each dye
- the percentage yield
- size of reaction vessels
- energy...
Enzyme technology
In this activity, students are asked to make a bioreactor containing an immobilised enzyme and use it to produce lactose reduced milk. They then assess the effect that temperature has on the enzyme driven reaction within the bioreactor.
